DESCRIPTION
30
Host:Printer
Selected
HSLCT
O16
This status output, generated by the
printer, goes high to indicate that the
printer is selected.
Connects to the
SELECT input to the Host.
Refer to
Section 4 of the IEEE STD 1284
(Reference 1) for use of this pin in ECP
and EPP modes.
6
nHost:Printer Error
nHERR
O16
This status output, generated by the
printer, goes low to indicate an error
condition at the printer. Connects to the
ERROR input to the Host.
Refer to
Section 4 of the IEEE STD 1284
(Reference 1) for use of this pin in ECP
and EPP modes.
5,8,13,15
-18, 20
Host:Data[0:7]
HD[0:7]
I/O16,
PU
Parallel port bi-directional data bus
connected to host system is used by
SPP, ECP and EPP to transfer data
between the host CPU and peripherals.
Refer to Section 4 of the IEEE STD 1284
(Reference 1) for use of this pin in ECP
and EPP modes.
PARALLEL PORT PASS-THROUGH INTERFACE PINS
29
nPass-Through:
Strobe
nPSTB
O16
An active low pulse on this output is used
to strobe printer data into the printer.
Connects to the STROBE input on the
next device along the chain. Refer to
Section 4 of the IEEE STD 1284
(Reference 1) for use of this pin in ECP
and EPP modes.
27
nPass-Through:
Auto Line Feed
nPALF
O16
This output goes low to cause the printer
to automatically feed one line after each
line is printed. Connects to the AUTOFD
input on the next device along the chain.
Refer to Section 4 of the IEEE STD 1284
(Reference 1) for use of this pin in ECP
and EPP modes.
